Take into account that -4π is equivalent to 0 or 2π. Then, you have:

[tex]\begin{gathered} \sin 0=0 \\ \cos 0=1 \\ \tan 0=\frac{\sin 0}{\cos 0}=0 \\ \cot =\frac{\cos 0}{\sin 0}=\text{undefined} \\ \sec 0=\frac{1}{\cos 0}=\frac{1}{1}=1 \\ \csc 0=\frac{1}{\sin 0}=\frac{1}{0}=\text{undefined} \end{gathered}[/tex]
